The object of this standard is to lay down the performance requirements of colour television receivers to ensure quality and reliability. The limits of performance have been so chosen as to ensure quality of such receivers and at the same time ensure sufficient freedom in design by the manufacturers. The performance requirements have also been so chosen as to provide consumer satisfaction and in-built safety measures. This Indian Standard was originally published in 1983 on a priority basis and was based on: a) The tentative specification of Department of Electronics, Government of India; b) The measurements carried out on colour television receivers at Research Department, All India Radio, and at CEERI, Pilani, organized by Department of Electronics which formed the basis for the tentative specifications of Department of Electronics, Government of India; and c) The limits of performance requirements in respect of monochrome TV receivers as laid down in IS 4547 : 1978 `Specification for receivers for monochrome television broadcast transmissions'.

If a receiver fails in any one of the acceptance tests, it shall be called defective. If the number of defectives found in the first sample (see col 2) is zero (see col 5), the lot shall be considered as conforming to the acceptance tests. If the number of defectives is as equal to or greater than two (see col 6), the lot shall be considered as not conforming to the acceptance tests. B-3.2 If the number of defectives is equal to one, further sample of receivers shall be taken according to col 3 of Table 3 and tested for all the acceptance tests. If the number of defectives in the combined sample (see col 6), the lot shall be considered as conforming to the acceptance tests otherwise rejected.

The following parameters though considered important could not be included in the standard due to lack of data and would be included subsequently with the built up of expertise: a) b) c) d) e) Chrominance signal demodulation, Delayed and undelayed chrominance signal mismatching, Colour killer response time, Convergence errors, and Colour saturation control. A scheme for labelling environment friendly products known as ECO Mark is introduced at the instance of the Ministry of Environment and Forests. The ECO Mark shall be administered by the Bureau of Indian Standards (BIS) under the BIS Act, 1986 as per the Resolution No. 71 dated 20 February 1991 published in the Gazette of Government of India, under the Environment (Protection) Act, 1986. For a product to be eligible for ECO Mark it shall also carry the Standard Mark of BIS for quality besides meeting additional environment friendly (EF) requirements. The EF requirements for Monochrome television receivers are being included through this Amendment to this standard. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 `Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. Bureau of Indian Standards BIS is a statutory institution established under the Bureau of Indian Standards Act , 1986 to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country. Copyright BIS has the copyright of all its publications. No part of these publications may be reproduced in any form without the prior permission in writing of BIS. This does not preclude the free use, in the course of implementing the standard, of necessary details, such as symbols and sizes, type or grade designations. Enquiries relating to copyright be addressed to the Director (Publications), BIS. Review of Indian Standards Amendments are issued to standards as the need arises on the basis of comments. Standards are also reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision. Users of Indian Standards should ascertain that they are in possession of the latest amendments or edition by referring to the latest issue of `BIS Catalogue' and `Standards : Monthly Additions'. This Indian Standard has been developed from Doc No.: LTD 20 (3090).
